The Sentinels are the guardians of the peaceful Principality of Ororos. Like the rest of the Principality's citizens, the Sentinels have celestial bloodlines that are still evident in small amounts to this day. Their focus with the blade is unmatched, and they train unceasingly to hone their skills. The Sentinels rarely see battle, as their reputation so far precedes them that few are foolhearty enough to encroach on their shores.
